Try reading Jeremiah 18, the potter and clay chapter.
There’s no individual persons on the potters wheel - it’s the nation of Israel...
You're missing the whole point. You've got man-centered theology. Where is God in your theology? Letting man take the wheel?
The Potter (God) doesn't form individual persons? Then who does? The clay forms itself? No. The Potter forms the clay. We are all clay. God is the Potter.
2Ti 2:21 Therefore, if anyone cleanses himself from what is dishonorable, he will be a vessel for honorable use, set apart as holy, useful to the master of the house, ready for every good work.
Who can bring a clean thing out of an unclean? not one. (Job 14:4)
For it is God which worketh in you both to will and to do of his good pleasure. (Philippians 2:13)
God determines whether we are vessels of honor or dishonor. "Cleanse myself" is relative language. If I "cleanse myself", it is really God who worked in me.
It’s what we do that determines if we become vessels of honor or dishonor.
Hath not the potter power over the clay, of the same lump to make one vessel unto honour, and another unto dishonour? (Romans 9:21)
You appear to say, "No! We take the potter's wheel for ourselves!"
I know the fact that it is our will that’s involved there, is very inconvenient to Calvinism and to the philosophy of fatalistic determinism known as reformed doctrine.
Our will is involved, but it is not any part of the driving force. God is the driving force.
(For the children being not yet born, neither having done any good or evil, that the purpose of God according to election might stand, not of works, but of him that calleth) (Romans 9:11)
